WILLIAM BAKER, OF CINCINNATI, OHIO.

soRU B BRUSH.

To all whom it may concern:

Be it known that WILLIAM BAKER, a citi- Zen of the United States ofAmerica, residing at Cincinnati, in the county of Hamilton and State ofOhio, has invented new and useful Improvements in Scrub Brushes, ofwhich the following is a specification.

At present, a bucket and sponge are used. for scrubbing floors and wallsand especially those of railroad cars, and to avoid this tedious method,it is the purpose of the present invention to provide, in a scrub brush,a construction for keeping the brush supplied with water and soap, thebrush having a handle whereby the operator may easily manipulate thebrush and thereby insure reaching all parts of the surfaces beingscrubbed.

Another purpose is to provide a pair of.

brushes rigidly connected, with a perforated v supply pipe for the Watermounted between certain of the bristles of the brush, in con-,

junction with liquid soap fountains or containers having perforationsregistering with perforations in thebacks of the brushes to keep thebristles thoroughly supplied with soa 3.

s till another purpose is the provision of means for retaining thefountains or containers on the backs or wood portions of the brushes. r

A further purpose is the provision of means forrigidlysecuring thehandle to and connecting the backs of the brushes to insure rigidity, thperforated pipe further insuring strength and durability.

A still further purpose is to provide a scrub brush of this designwherein a. metallic tubular handle is connected to the brush foroperating the same, together with means for connecting a water supplyhose to said handle to keep the brush supplied with water.

It is to be understood that the particulars herein given are in no waylimitative and that, while still keeping within the scope of theinvention, any desired modifications of detail and desired proportionsmay be made in the apparatus according to the circumstances.

The invention comprises further features and combinations of parts to behereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a plan view of the improved scrub brush constructed inaccordance with the invention.

Figure 2 is a longitudinal: sectional view through the twosections ofthe brush.

Figure 3 is a plan view of the brush.

Figured is a transversesectional view on line 44 of Figure 2.

Figure 5 is a plan view of the brush, showing the tubular handle whichis adaptedfor connection with a hose which supplies water to the brush.

Referring to the drawings, 1 and 2 designate the two sections of thebrush. The backs of the sections may be constructed of any suitablematerial, preferably wood or metal, and are provided with rows ofbristles 3. The backs of the sections of the brush between the rows ofbristles are perforated, as shown at 4, and mounted upon the backsarefountains; 5 for receiving liquid soap. The fountains are rectangular incross section and have. their bottoms provided with perforations 6 whichregister with perforations 4 in the backs of the sections of the brush.

The fountains seat, in depressed recesses 7 in the backs of the brushsections, there being a filler of rubber in the bottoms of the recessesto prevent leakage. Suitable U- shaped stays or straps8 straddle thefountains. the arms of the straps passing through openings in the backsof the brush sections,

there being'suitable nuts 9 threaded upon the to hold the strapssecurely in position and retain the fountains clamped to the backs ofthe brush sections. The fountains are provided with-filling openings 10which are closed by caps 11;

As shown in Figures .1 to 4, a handle 12 is provided which engages asocket 13 of a handle coupling device 14c. This device has lateral arms15 which are secured by screws or the like 16 to the backs of the brushsections, thereby holding the brush sections rigidly in alignment. Thehandle is disposed at an angle to the brush sections 'so that theoperator may readily manipulate the brush over the surfaces to bewashed.

Also carried by the backs of the brush sections between the central rowsof bristles are perforated pipes 17 which are secured in any suitablemanner to the backs of the brush sections. The perforations of thesepipes are positioned so as to direct water therefrom divergently whenthe brush sections are moving over-the surface being scrubbed. Thesepipe sections are connected by a T-union 18 and due to the pipe sectionsbeing secured to nipple 19 to which a reducer 20 is connected.

A hose 21 connects ith the reducer and is provided with a suitable valveor cut-ofi' 22- for controllingthe supply of water to the brush duringthe operations of the xb'rushi, Thehose may be of the generalconstruction and may connect with any suitable source of supply, such asis provided with a main control valve 23,'for turning off the supply ofWater when finishing with the use of the brush.-' 7 t 1 In Figure 5, itwill be noted that the T-' union 24' is slightly modified and connectedto one legof the union is an elbow 25 to which a short pipe section 26is connected. A second elbow 27 is connected to the-short pipe section26 and carries a long tubular pipe section 28 which constitutes a handleand to which the hose may be connected for supplying water to the brush,which is identical inrconstruction with that shown in Figuresl to 4:. Bythis method of connecting the handle, 28: to the brush, it is possibleto supply the water through thehandle and yet allow the handle" to moverelative. to the brush as it. is moving over the surface being 7 soaptothe bristles through the perforations, and means'for. supplying water tothe bristles of the brushsectionsL 1 q 2.1m a scrub brush, thecombination with a pair of aligned brush sections,"means connecting thebacks of the brush sections, the
